I can’t believe what I just did…
I was setting up the neopixel pushbutton to record the demo video to post on here, plugged a custom extension cable into the Arduino I’m testing with, hooked up each wire, plug the Arduino into a USB port… POP. I had + and - reversed on the intermediate cable… I should’ve bought two packs of these LEDs…
EDIT: Ok when I said I blew up a LED, the first time was just a brown mark inside. This one was a bit more forceful, despite still only being 5V at whatever current my PC limits its USB ports to…
@marmil Well the enameled wires are the same color yep, but I clip each one to a different length and make note of which one’s which, then I attach insulated color-coded wires (which are too thick to go right into the switch) to the ends after assembling the switch. The reversed polarity was just a derp with which way I connected the extender cable at the Arduino end (I just shoved a group of three jumper wires in - backwards)
I use a lot of ‘salvage’ wire for projects so sometimes I’ll have a purple and yellow wire (or whatever) for my leads. I find it helpful to put a short piece of red or black shrink tube on the end as a ‘label’.
@allanGEE I sort of salvage parts, too. I have a few bundles of those rainbow-colored jumper wires commonly advertised for the Raspberry Pi. For short wires like this, I can easily just peel off the color I need, chop the ends off, maybe cut the wire in half, strip it, then good to go. Technically, the enameled wire was also salvaged from some kit or something, as I found a small reel of it in a box despite never buying any…
PS: The color-coding I used for this button is mostly the same as the LED strips I bought; Red=5v,Green=Data in,White=Ground,Yellow=Data out (the strips use green at both ends )
